Issues
addressed and main goals of research:
Search
for and investigation of double-neutrino and neutrinoless modes of
double beta decay, clarification of the neutrino nature, Majorana or
Dirac, and absolute neutrino mass scale and hierarchies. Search for
the neutrino magnetic moment and dark matter. Investigation of
galactic and extragalactic neutrino sources, diffusive neutrino
cosmic background, and search for exotic particles (monopoles). Use
of the neutrino detector for a distant investigation of processes
inside of the reactor core of the Kalinin Nuclear Power Plant (KNPP).
Search for sterile neutrinos. Spectroscopy of nuclei far from
stability. Development of new methods for charged and neutral
particle detection.
Expected
results in the current year:
Data
taking in the 2β0ν decay
measurements of 106Cd, 82Se,
with the SuperNEMO spectrometer. Processing of the data collected in
the GERDA experiment, set T1/2 limits
for different 2β
-decay modes.
Processing
of experimental data and determination
of T1/2(2β0ν) for 48Ca, 96Zr, 130Te, 116Cd, 82Se
and 76Ge.
Data
taking with the HPGe-based low-background νGeN spectrometer
at the Kalinin Nuclear Power Plant. Search for a signal of coherent
neutrino scattering on the germanium nuclei. Data taking start
searching for the neutrino magnetic moment at the sensitivity level
of ~ (5-9)·10 -12 µB after
several years of data taking.
Continuation
of data taking in the EDELWEISS experiment with new detectors
operating with an energy threshold of 0.1 keV suitable for the
extra-low mass WIMP region. Analysis of previously accumulated data,
determination of parameters for light dark matter for the mass
region below 1 GeV/c 2.
Start of the Ricochet phase of the experiment for precision CEnNS
studuing at ILL with the detectors developed by EDELWEISS.
Start
of data taking in the tone-scale LEGEND experiment, searching
for 2β2ν decay
of 76Ge.
Data
taking with eight clusters of the BAIKAL-GVD neutrino
telescope. Search for and study of high-energy neutrinos of the
astrophysical nature. Constructing and commissioning of new detector
clusters. Development and testing of new data acquisition and data
transmission systems aiming at a lower energy threshold (Baikal
project).
Investigation
of KLL and KMM Auger electrons in 67Ga
and 152,154,155Eu
decays.
Development
and testing of new low-threshold (~ 200 eV) HPGe detectors for
searching for the coherent neutrino scattering, as well as of
plastic scintillator detectors for their active shielding.
Results
of search for sterile neutrinos on the 2016-2021 data accumulated by
the DANSS spectrometer. Precision estimates of the gamma and neutron
background at the location of the DANSS spectrometer (room A336
under the reactor of the 4th power unit of the KNPP). R&D
results of the spectrometr modernization.
The
radiochemical laboratory of the 2nd class will be commissioned in
the DLNP; equipment for the manufacture of radioactive sources for
brachytherapy of cancer diseases will be installed; important work
for obtaining of a sanitary and epidemiological certificates for the
radiochemical laboratory will be concluded.
Continuation
of the MONUMENT project. Preparation for 2022 PSI accelerator run
(purchasing of detectors and targets, update of the cryostats). Data
taking. Analysis of previously accumulated data.
